Description

The present invention relates to a laminate such as an ID card or a booklet having an IC module, a laminate issuing system for issuing the laminate, and a laminate issuing method, and in particular, a laminate capable of issuing while improving the appearance of the laminate and the laminate thereof. It relates to the laminated body issuing system and the laminated body issuing method to issue.

Laminates such as ID cards such as national ID cards, driver's licenses, employee ID cards, and information pages constituting passports include IC modules and are made of plastic materials having heat resistance and durability as a whole. Patent Document 1 describes an example of a laminate issuing system that manufactures and issues such an ID card. In the process of manufacturing and issuing an ID card, there is a process of forming unique information such as a face image and an ID mark that identifies the owner of the card, a process of mounting an IC module inside the ID card, and a process of mounting the IC module. Includes the process of writing specific information in.

International release WO2018 / 159767

When issuing an ID card or the like in this way, both the unique information such as the face image and the ID mark printed and formed on the face of the ticket and the specific information to be written in the IC module included in the ID card are the same. It needs to be unique information that can identify the owner of the card. When any of these information is irrelevant to the unique information for identifying the owner of the card, that is, between the unique information such as a face image or ID mark and the specific information written in the IC module. This is because if there is no relevance, it can be determined that the card is forged.

Here, when a face image, an ID mark, or the like is first formed on the face of an ID card or the like and information is written to the IC module later, the issuing device side inputs the information such as the face image or the ID mark by a camera or an OCR reader. It is necessary to recognize it and search the database or the like for the information written to the IC module associated with it. If the method is to simply write to the IC module in the order in which it was issued without reading information such as the face image and ID mark, the information written to the IC module will be written when the order of the cards is changed due to poor transportation or the like. This is because there is a risk that it will not be associated with information such as a face image or an ID mark.

However, it takes a long time to directly recognize the face image by the camera, and there is a possibility that the information written to the corresponding IC module is mistaken due to erroneous recognition or the like. Further, depending on the ID card or the like, it may not be preferable to display the ID mark or the like for security or design reasons. On the other hand, when forming a face image, an ID mark, or the like on the face of an ID card, it is conceivable to form a visible barcode or the like at the same time. However, such a code is not necessary for normal use by the owner of the ID card and may spoil the appearance. In addition, this code may be read illegally and misused.

This disclosure has been made in view of such a situation, and even after the unique information is formed, the information should be surely written to the IC module corresponding to the unique information without spoiling the appearance as much as possible.

Hereinafter, an example of the laminated body and the laminated body issuing system of the present disclosure will be described with reference to the drawings and the like. However, the laminate and the laminate issuing system of the present disclosure are not limited to the embodiments and examples described below.

In addition, each figure shown below is shown schematically. Therefore, the size and shape of each part are exaggerated as appropriate to facilitate understanding. Further, in each figure, hatching showing a cross section of the member is omitted as appropriate. Numerical values such as dimensions and material names of each member described in the present specification are examples of embodiments, and are not limited thereto, and can be appropriately selected and used. In the present specification, terms that specify a shape or a geometric condition, such as parallel, orthogonal, and vertical, are used to include substantially the same state in addition to the exact meaning.

1. 1. First Embodiment of Laminated Body The first embodiment of the laminated body of the present disclosure will be described. FIG. 1 is a plan view of the ID card 10 according to the first embodiment as viewed from the normal direction of the main surface thereof. Further, FIG. 2 is a view from the lower side of FIG. 1 when the ID card 10 is cut in a cross section passing through the AA line overlapping the hologram 315 of the ID card 10, the IC module 200, and the face image unit 310 in FIG. It is sectional drawing of the ID card 10. The ID card 10 is an example of the laminated body of the present disclosure.

In the ID card 10, the invisible light absorption layer 140 is laminated on one surface of the transfer medium 1, and the first transparent layer 150 is further laminated on the surface of the invisible light absorption layer 140 opposite to the transfer medium 1 side. It has a configured configuration. A printing unit 300 and a facial image unit 310 are arranged in a part between the first core layer 170 arranged on one surface of the transfer medium 1 and the adjacent invisible light absorbing layer 140. Further, a hologram 315 is arranged in a part between the invisible light absorption layer 140 and the first transparent layer 150. Further, the transfer medium 1 includes an IC module 200 including an IC chip inside thereof.

When the ID card 10 is viewed in a plan view from the surface on which the first transparent layer 150 is arranged, the printing unit 300, the hologram 315, the laser-printed characters 313 and the ID mark 314, the face image 311 formed on the face image unit 310, etc. Can be visually recognized. The invisible light absorbing layer 140 and the first transparent layer 150 have transparency that transmits at least a part of visible light.

The face image unit 310 is composed of a color face image 311 of the owner of the ID card 10 and an invisible ink layer 312 arranged so as to partially overlap the face image 311. The invisible ink layer 312 constitutes, for example, a two-dimensional bar code and transmits visible light. Therefore, it is difficult to visually recognize the two-dimensional bar code formed by the invisible ink layer 312 even when irradiated with visible light.

The invisible ink layer 312 becomes visible by irradiating ultraviolet rays in a specific wavelength range, which is invisible light, to excite visible light and develop fluorescent color. However, the invisible light absorption layer 140 and the first transparent layer 150 are laminated on the upper layer of the face image unit 310. Of these, the invisible light absorbing layer 140 absorbs ultraviolet rays in at least a part of the wavelength range contained in the ultraviolet rays in a specific wavelength range in which the invisible ink layer 312 excites visible light to develop fluorescent color.

Therefore, even if ultraviolet rays in the partial wavelength range are irradiated, the invisible ink layer 312 does not excite visible light to develop fluorescent color, and the two-dimensional bar code formed by the invisible ink layer 312 can be visually recognized. It cannot be read by the camera. On the other hand, consider the case where the face image portion 310 and the invisible light absorption layer 140 are formed on the transfer medium 1 (intermediate laminate described later). In this case, before laminating the invisible light absorbing layer 140, the two-dimensional bar code formed by the invisible ink layer 312 of the intermediate laminate can be visually recognized by irradiating a wider range of ultraviolet rays in a specific wavelength range. It can be read by the camera.

Therefore, the information of the invisible ink layer 312 can be read relatively easily with respect to the intermediate laminated body before the invisible light absorption layer 140 is laminated, and the information can be reliably written to the IC chip corresponding to the read information. Can be done. On the other hand, in the state of the ID card 10 in which the invisible light absorbing layer 140 is laminated on the intermediate laminated body, it becomes difficult to read the information of the invisible ink layer 312 due to the absorption of the invisible light of the invisible light absorbing layer 140, and the ID card 10 is unintentionally. Information can be suppressed from being read. Hereinafter, the details of the configuration of the ID card 10 according to the first embodiment will be described.

(A) Transfer medium As shown in FIG. 2, the transfer medium 1 has a second transparent layer 160, a second core layer 180, an additional intermediate layer 130, an IC module holding layer 110, an intermediate layer 120, and a first layer from the lower layer side. It has a configuration in which one core layer 170 is sequentially laminated. The IC module holding layer 110 is a layer that holds the IC module 200 and the antenna 230. However, the transfer medium 1 does not necessarily have to include all of these layers, and at a minimum, it may have a layer corresponding to the first core layer 170 which is a base material.

As will be described later, the first core layer 170 may be a layer in which a face image portion 310, which is a print layer, can be formed on one surface thereof, and an invisible light absorption layer 140, which will be described later, can be laminated. Further, it is preferable that the transfer medium 1 is provided with the IC module 200, the antenna 230, and the IC module holding layer 110 for holding the IC module 200 and the antenna 230 on the other surface side in addition to the first core layer 170. On the contrary, the transfer medium 1 may further include a layer other than the above-mentioned series of layers.

(I) First core layer and second core layer The first core layer 170 and the second core layer 180 are both white or colored resin base materials, and the invisible light absorption layers 140 and the second, respectively. The printed portion 300 can be formed on the laminated surface of the transparent layer 160 as needed. In this case, after the ID card 10 is manufactured, the printing unit 300 formed on the first core layer 170 and the second core layer 180 through the transparent invisible light absorption layer 140, the first transparent layer 150, or the second transparent layer 160. Characters and patterns can be clearly seen.

As the members of the first core layer 170 and the second core layer 180, various white or colored plastic sheets can be widely used, and the following single films or composite films thereof can be used. For example, polyethylene terephthalate (PET), PET-G (terephthalic acid-cyclohexanedimethanol-ethylene glycol copolymer), polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polycarbonate, polyamide, polyimide, cellulose diacetate, cellulose. Triacetate, polystyrene, ABS, polyacrylic acid ester, polypropylene, polyethylene, polyurethane, etc.

(Ii) First transparent layer and second transparent layer The first transparent layer 150 is laminated on the outside of the invisible light absorption layer 140. The second transparent layer 160 is laminated on the outer side of the second core layer 180 and constitutes an end face on the opposite side of the transferred medium 1 from the first core layer 170. As the first transparent layer 150 and the second transparent layer 160, materials having the same quality as those of the first core layer 170 and the second core layer 180 are usually used, and in particular, transparent materials are often used. The materials of the first transparent layer 150 and the second transparent layer 160 may be any material having adhesiveness due to heat, but even when the first transparent layer 150 and the second transparent layer 160 themselves do not have adhesiveness due to heat. , A layer of a known transparent adhesive that generates an adhesive force by heat or the like is added between the invisible light absorbing layer 140 and the first transparent layer 150, and between the second core layer 180 and the second transparent layer 160. By forming, both can be integrated. This point is the same for the adhesion between the other two layers.

(Iii) IC module, antenna and IC module holding layer The IC module holding layer 110 is an IC module 200 and an antenna arranged in a section sandwiched between the first core layer 170 and the second core layer 180 of the transfer medium 1. It is a layer that holds 230. The IC module holding layer 110 includes a substrate-compatible layer 111 and an IC chip-compatible layer 112, and has a storage space 320 that is a recess that straddles the substrate-compatible layer 111 and the IC chip-compatible layer 112. FIG. 3A is a cross-sectional view of the IC module 200, and FIG. 3B is a diagram showing a positional relationship between the antenna 230 and the IC module 200.

The IC module 200 includes an IC chip body 210 composed of an IC chip 211 and a sealing resin 212 covering the outer periphery thereof, and a substrate 220 that supports the IC chip body 210. Further, both ends of the antenna 230 wound in a loop are connected to the IC module 200. Both ends thereof are electrically connected to a connection pad (not shown) of the IC chip 211 arranged inside the IC chip body 210.

The IC chip 211 is an integrated circuit in which various circuit elements are built in a semiconductor substrate such as silicon, and has a thin, substantially rectangular parallelepiped structure. The IC chip 211 is provided with, for example, various circuits formed on one surface thereof and a connection pad (not shown) described above. By electrically connecting both ends of the antenna 230 to the connection pad of the IC chip 211, the IC chip 211 can perform various functions.

For example, the antenna 230 is electromagnetically coupled by receiving an electromagnetic wave of a predetermined frequency from the outside, and the operating power of the IC chip 211 is taken out from the electromotive force generated in the antenna 230 to drive the CPU. In addition, information is decoded from the voltage pattern of the electromotive force, various operations are performed, data is read from the memory, and data is written to the memory. Further, it has a function of converting transmission information into radio waves having a predetermined frequency and transmitting the transmission information via the antenna 230, if necessary.

On the other hand, the antenna 230 may perform proximity communication using, for example, an HF frequency band of 13.56 MHz, or may perform communication using another, for example, a UHF frequency band of 920 MHz. In any case, the antenna 230 is arranged so that the IC chip 211 performs non-contact communication with an external reader / writer (information reading / writing device). When the ID card 10 is held over the reader / writer, the antenna 230 generates electric current due to a magnetic field or the like formed by the reader / writer to supply electric power to the IC chip 211. As a result, the IC chip 211 can be driven, and information can be transmitted / received and data can be rewritten by non-contact communication with the reader / writer.

The antenna 230 is typically formed of a coated conductor in which the circumference of the copper wire is coated with an insulating member. In addition to this, select a copper alloy wire such as Cu—Ni, Cu—Cr, Cu—Zn, Cu—Sn, Cu—Be, or various metal wires such as iron, stainless steel, and aluminum, and a metal alloy wire. You can also do it. By using the coated conductor wire, antenna formation can be inexpensive as compared with, for example, a copper foil etching method. However, the antenna 230 may be punched or etched from copper foil, aluminum foil, or the like.

The storage space 320 formed in the IC module holding layer 110 constitutes a recess having a shape slightly larger than the outer shape of the IC module 200. The storage space 320 is provided in a first recess provided on the substrate-compatible layer 111 side for accommodating the substrate 220 constituting the wide brim and on the IC chip-compatible layer 112 side for accommodating the IC chip body 210 in a cross-sectional view. The second recess is provided. The width of the second recess is smaller than that of the first recess. In a state where the IC module 200 is housed in the storage space 320 of the IC module holding layer 110, a slight gap is formed around the IC module 200. These gaps are the opening 321 which is the gap on the substrate corresponding layer 111 side and the opening 322 which is the gap on the IC chip corresponding layer 112 side.

By providing the openings 321 and 322 around the IC module 200 arranged in the IC module holding layer 110, it is possible to suppress the internal stress when the ID card 10 is bent directly from being applied to the IC chip body 210, and the IC. It is possible to prevent damage to the chip 211 and disconnection between the IC chip 211 and the antenna 230. Further, the antenna 230 is sandwiched between the substrate-compatible layer 111 and the IC chip-compatible layer 112. As the members of the substrate-compatible layer 111 and the IC chip-compatible layer 112 constituting the IC module holding layer 110, the members exemplified in the first core layer 170 and the second core layer 180 can be used. In addition, a resin film for a flexible printed substrate having flexibility such as a glass epoxy resin or a polyimide resin may be used.

(Iv) Intermediate layer and additional intermediate layer The intermediate layer 120 and the additional intermediate layer 130 are layers laminated on one surface and the other surface of the IC module holding layer 110, respectively. These two layers are laminated so as to block the vertical direction of the storage space 320 formed in the IC module holding layer 110 for accommodating the IC module 200. As a result, the airtightness of the storage space 320 is maintained, and deterioration of the IC chip 211 due to the ingress of moisture or the like from the outside can be suppressed.

Further, the unevenness on the front and back surfaces of the IC module holding layer 110 generated by the storage of the IC module 200 can be absorbed by the intermediate layer 120 and the additional intermediate layer 130. Therefore, it is possible to obtain the ID card 10 having a good appearance by reducing the unevenness on the outermost surface. As the members of the intermediate layer 120 and the additional intermediate layer 130, the members exemplified by the first core layer 170 and the second core layer 180 can be used.

(B) Invisible light absorption layer The invisible light absorption layer 140 is a transparent base material that transmits visible light. Further, the invisible light absorption layer 140 has a property of absorbing invisible light having a predetermined wavelength. In the present embodiment, the invisible light absorption layer 140 is configured to absorb ultraviolet rays having a predetermined wavelength. The invisible light absorbing layer 140 may contain a resin obtained by reaction-bonding a reactive ultraviolet absorber. Specifically, non-reactive ultraviolet absorbers such as salicylate-based, benzophenone-based, benzotriazole-based, substituted acryloylnitrile-based, nickel chelate-based, and hindered amine-based, which are known organic ultraviolet absorbers, include, for example, vinyl groups. Additive polymerizable double bonds such as an acryloyl group and a metaacryloyl group, or those having an alcoholic hydroxyl group, an amino group, a carboxyl group, an epoxy group, an isocyanate group or the like can be used. Examples of such a reactive ultraviolet absorber include those having the structural formula exemplified in JP-A-8-39946.

As a method for reacting and fixing such a reactive ultraviolet absorber to a resin, various methods can be used. For example, a known monomer, oligomer or a resin component of a reactive polymer and the above-mentioned addition-polymerizable double bond. A copolymer can be obtained by radical polymerization with a reactive ultraviolet absorber having the above. When the reactive ultraviolet absorber has a hydroxyl group, an amino group, a carboxyl group, an epoxy group, an isocyanate group, etc., a thermoplastic resin having the above-mentioned reactive group and reactive group is used, and a catalyst is used if necessary. Can be used to react and fix the reactive ultraviolet absorber to the thermoplastic resin by heat or the like. Examples of the monomer component copolymerizing with the reactive ultraviolet absorber include those exemplified in the above-mentioned literature.

In the visible light and ultraviolet wavelength regions, techniques for forming an ultraviolet or visible light absorption layer that selectively and strongly absorbs only a specific wavelength region are described in, for example, Japanese Patent Application Laid-Open No. 2005-120232 and Patent No. 6062968. Also shown in.

On the other hand, the invisible light absorption layer 140 may be configured to absorb infrared rays instead of ultraviolet rays having a predetermined wavelength. For example, it is possible to use a biaxially oriented film in which an invisible light absorbing layer 140 is laminated with three layers of polyester, to which an immonium-based compound, a diimonium-based compound, a phthalocyanine compound, an aminium compound, a polymethine compound, or the like is added as an infrared absorber. can. Such an infrared absorber-containing film is exemplified in, for example, Japanese Patent No. 5052716.

As described above, it is also possible to impart laser light printability to the invisible light absorption layer 140. The invisible light absorption layer 140 laminated adjacent to the transfer medium 1 described above is a transparent base material, and is a layer capable of displaying black characters and patterns by irradiation with a laser beam having a predetermined wavelength. The invisible light absorption layer 140 contains a laser light color development accelerator, and when a laser beam having a predetermined wavelength is irradiated, the laser light color development accelerator generates heat and burns the surroundings to blacken the surroundings. Therefore, by drawing the laser beam to be irradiated, desired characters and patterns can be displayed in black. However, it is not necessary to impart such laser beam printability to the invisible light absorption layer 140. When imparting laser light printability to the invisible light absorption layer 140, a material to which a laser light color development accelerator such as a metal oxide is added to the above-mentioned material is preferably used.

(D) Face image unit As shown in FIGS. 2 and 4, the face image unit 310 is a print layer arranged so as to be sandwiched between the transfer medium 1 and the invisible light absorption layer 140. The face image unit 310 is composed of a first print layer of the face image 311 which is two print layers and a second print layer of the invisible ink layer 312 arranged so as to partially overlap the face image 311. The face image 311 can be visually visually recognized directly by irradiation with visible light, but since the invisible ink layer 312 transmits visible light, it is difficult to clearly visually recognize the face image 311. As shown in FIG. 4, the transfer medium 1 to which the face image portion 310 and the invisible light absorption layer 140 are added is referred to as an intermediate laminate 2 for convenience. Further, the print layer may be formed by any method such as electrostatic photo printing, thermal transfer from an ink ribbon, and inkjet printing, in addition to methods such as offset printing, gravure printing, and silk printing.

As one of the specific examples of forming the face image portion, the method by thermal transfer will be described below.

FIG. 5A is a cross-sectional view of the ink ribbon 400 cut along the plane-sequential formation direction of the ink layer 430 and the thickness direction of the ink ribbon 400. FIG. 5B is a plan view of the ink ribbon 400 with respect to the surface on the ink layer 430 side. The face image unit 310 is transferred to an intermediate transfer sheet, which will be described later, using an ink ribbon 400 provided with an ink layer 430 in a surface sequence as shown in FIGS. 5 (a) and 5 (b), and then covered. It can be formed by re-transferring to the surface side of the transfer medium 1 where the first core layer 170 is located.

The ink ribbon 400 has a configuration in which the back surface layer 410, the support base material 420, and the ink layer 430 are laminated in this order from one surface side. Further, the ink layer 430 of the ink ribbon 400 includes a colored ink portion 431 which is yellow ink (Y), magenta ink (M), cyan ink (C), and black ink (K) along the longitudinal direction of the ink ribbon 400. , The invisible ink unit 432, which is the invisible ink (X), is arranged in a plane-sequential manner. However, the ink ribbon 400 may be provided with only the colored ink portion 431 in a surface-sequential manner, and the invisible ink portion 432 may be formed on another ink ribbon or film.

First, the invisible ink portion 432, which is the invisible ink (X), is overlapped with the receiving layer of the intermediate transfer sheet (not shown) facing each other, and is thermally transferred to the intermediate transfer sheet side as a predetermined image by the thermal pressure from the thermal head (not shown). .. Next, each of the colored ink portions 431 of the yellow ink layer (Y), the magenta ink layer (M), the cyan ink layer (C), and the black ink (K) of the ink ribbon 400 is sequentially formed, and a part of the invisible ink portion 432 is sequentially formed. It is laminated so as to face the receiving layer of the heat-transferred intermediate transfer sheet.

Then, due to the heat pressure from the thermal head, the images of each color are thermally transferred to the intermediate transfer sheet side so as to overlap each other. However, the invisible ink portion 432 does not need to be directly superposed on the upper layer of each colored ink portion 431, and the invisible ink portion 432 may be formed on the upper side of each colored ink portion 431 via another sheet. At this time, it is preferable that a part of the invisible ink portion 432 overlaps with each colored ink portion 431 in a plan view along the thickness direction of the transfer medium 1.

After that, as will be described later, the intermediate transfer sheet on which a series of images are formed approaches the transferred medium 1 so as to face each other and is conveyed together. Further, a heat pressure is applied by hot stamping from the surface of the intermediate transfer sheet opposite to the surface to be transferred, so that a color image formed by the colored ink portion 431 and an invisible image formed by the invisible ink portion 432 formed on the intermediate transfer sheet can be obtained. Is thermally transferred onto the transfer medium 1. The details of this point will be described later.

Further, as another specific example of forming the face image portion, there is also a method of forming all or a part of the face image portion by inkjet printing. When the entire face image portion is formed by inkjet printing, the above-mentioned ink ribbon and intermediate transfer sheet are unnecessary, and the process can be simplified. On the other hand, when only the invisible ink (X) is formed by inkjet printing in the face image portion, the layout of the ink ribbon is different from that of FIG. 5 (b). In FIG. 5B, in the ink layer 430 of the ink ribbon 400, the colored inks of the yellow ink layer (Y), the magenta ink layer (M), the cyan ink layer (C), and the black ink (K) of the ink ribbon 400. The invisible ink unit 432 and the invisible ink unit 432, which is the invisible ink (X), are arranged in a surface-sequential manner, but the invisible ink (X) is unnecessary because it is performed by inkjet printing, which is a separate step.

In the latter case, first, the colored ink portions 431 of the yellow ink layer (Y), the magenta ink layer (M), the cyan ink layer (C), and the black ink (K) of the ink ribbon sequentially receive the intermediate transfer sheet. Stacked facing the layers. Then, due to the heat pressure from the thermal head, the images of each color are thermally transferred to the intermediate transfer sheet side so as to overlap each other. After that, as will be described later, the intermediate transfer sheet on which a series of images are formed approaches the transferred medium 1 so as to face each other and is conveyed together. Further, by applying thermal pressure by hot stamping from the surface of the intermediate transfer sheet opposite to the surface to be transferred, the color image formed on the intermediate transfer sheet by the colored ink portion 431 is thermally transferred onto the transfer medium 1. Will be done. After that, the invisible ink ejected from the ink head forms a second print layer which is the invisible ink layer 312.

In this way, regardless of the method of forming the face image portion, the face image portion 310 composed of the face image 311 and the invisible ink layer 312 is formed on the surface of the transfer medium 1. The face image 311 is a color image showing the face image of the owner of the ID card 10, and the invisible ink layer 312 is a two-dimensional bar code that cannot be visually recognized by irradiation with visible light. The pattern formed by the invisible ink layer 312 is not limited to the two-dimensional bar code, and may be any information such as a one-dimensional bar code, alphanumerical characters, characters, symbols, and figures that can be recognized.

The invisible ink layer 312 is formed of an ink that becomes visible by irradiating ultraviolet rays in a specific wavelength range, which is invisible light, to excite visible light and develop fluorescent color. Examples of the material that is excited by ultraviolet rays and emits visible light include fluorescein-based fluorescent dyes, coumarin-based fluorescent dyes, and rhodamine-based fluorescent dyes as dyes. Inorganic pigments include valium magnesium aluminometated with europium and manganese, zinc silicate activated with manganese, yttrium oxide activated with europium, yttrium sulfide activated with europium, zinc oxide, and germanium activated with manganese. Examples thereof include zinc oxide, yttrium of active limvanadate with europium, and the like.

Further, the invisible ink layer 312 may be formed of an ink that becomes visible by irradiating infrared rays in a specific wavelength range, which is invisible light, to excite visible light and develop fluorescent color. Materials that are excited by infrared light and emit visible light are also called up-conversion type illuminants, for example, erbium (Er), holmium (Ho), placeodium (Pr), terbium (Tm), neodium (Nd), gadolinium ( Contains at least one rare earth element selected from the group consisting of Gd), uropyum (Eu), samarium (Sm), terbium (Tb), dysprosium (Dy) and cerium (Ce) of the phosphor particles. Examples thereof include those whose base material is a halide or the like. Further, although there are some that overlap with the above, for example, the materials shown in JP-A-7-297475 can be mentioned.

In the present embodiment, the invisible ink layer 312 is formed of an ink that becomes visible by irradiating ultraviolet rays in a specific wavelength range, which is invisible light, to excite visible light and develop fluorescent color. In addition to this, the invisible light absorbing layer 140 absorbs ultraviolet rays in at least a part of the wavelength range contained in the ultraviolet rays in a specific wavelength range in which the invisible ink layer 312 excites visible light to develop fluorescent color. Therefore, due to the presence of the invisible light absorbing layer 140, the invisible ink layer 312 is irradiated with ultraviolet rays to excite visible light and develop fluorescent color, so that the two-dimensional bar code or the like composed of the invisible ink layer 312 can be easily visually recognized or read. It can be suppressed from being done.

Further, absorbing ultraviolet rays in at least a part of the wavelength range naturally includes absorbing all ultraviolet rays in a specific wavelength range in which the invisible ink layer 312 excites visible light to develop fluorescent color. Further, the invisible light absorbing layer 140 may be one that does not absorb ultraviolet rays in at least a part of the wavelength range contained in the ultraviolet rays in a specific wavelength range in which the invisible ink layer 312 excites visible light to develop fluorescent color.

At this time, it is preferable that the wavelength range of visible light that is excited and fluorescently developed is narrower than that in the case without the invisible light absorption layer 140. This is because even in this case, the effect of suppressing the visibility of the fluorescently developed invisible ink layer 312 and the readability by a machine can be expected. Furthermore, by making the color tone of the fluorescent color developed by irradiation with ultraviolet rays of the same wavelength different depending on the presence or absence of the invisible light absorbing layer 140, it is possible to detect forgery of either the invisible ink layer 312 or the invisible light absorbing layer 140. .. Such an ID card 10 contains, for example, a plurality of fluorescent dyes having different wavelengths from each other and excited and fluorescently developed in the invisible ink layer 312, and absorbs ultraviolet rays in a wavelength range that excites any of the fluorescent dyes. The invisible light absorption layer 140 may be selected so as to do so.

On the other hand, when the invisible ink layer 312 is formed of ink that becomes visible by exciting visible light and developing fluorescent color by irradiating infrared rays in a specific wavelength range, the invisible light absorption layer 140 is also included in this. Need to match. That is, the invisible light absorbing layer 140 should be selected to absorb infrared rays in at least a part of the wavelength range contained in the infrared rays in a specific wavelength range in which the invisible ink layer 312 excites visible light to develop fluorescent color. .. As a result, as in the above case, due to the presence of the invisible light absorbing layer 140, the invisible ink layer 312 is irradiated with infrared rays to excite visible light and develop fluorescent color, whereby the two-dimensional bar formed by the invisible ink layer 312 is formed. This is because it is possible to prevent the code or the like from being easily visually recognized or read.

(E) Hologram As shown in FIGS. 2 and 4, the hologram 315 is arranged so as to be sandwiched between the invisible light absorbing layer 140 and the first transparent layer 150. The hologram 315 of this embodiment is a volume hologram. However, the hologram 315 is not limited to this, and may be various optical elements such as an embossed hologram, a Lipman hologram, a color switch, a fantastic glass, and a hollow thread.

As will be described later, the hologram 315 of the present embodiment is formed in advance on the surface of the long invisible light absorbing layer 140 facing the first transparent layer 150 at predetermined intervals. However, the present invention is not limited to this, and may be formed in advance on the surface of the long first transparent layer 150 facing the invisible light absorbing layer 140 at predetermined intervals. As shown in FIG. 4, the ID card 10 is formed by laminating the hologram 315 and the first transparent layer 150 on the intermediate laminate 2.

The ID card 10 shown in FIG. 2 has an overall thickness of, for example, 800 μm. Of these, for example, the thickness of the invisible light absorbing layer 140 is 105 μm, and the thickness of the first transparent layer 150 is 50 μm. For the transfer medium 1, the thickness of the first core layer 170 is 105 μm, the thickness of the intermediate layer 120 is 40 μm, the thickness of the substrate-compatible layer 111 is 105 μm, and the thickness of the IC chip-compatible layer 112 is 150 μm. There is. The thickness of the additional intermediate layer 130 is 40 μm, the thickness of the second core layer is 105 μm, and the thickness of the second transparent layer 160 is 105 μm.
However, the thickness of each of the above layers is an example, and other combinations are allowed.

2. 2. Second Embodiment of the Laminated Body Next, as an example other than the ID card of the laminated body of the present disclosure, an information page according to the second embodiment and a booklet including the information page will be described. FIG. 6 is a schematic perspective view showing the booklet 20 according to the second embodiment. The information page 21 constituting the booklet is also an example of the laminated body of the present disclosure.

The booklet 20 has a structure in which a plurality of pages including a front cover 23, a back cover 24, and an information page 21 sandwiched between the front cover 23 and the back cover 24, each of which is substantially rectangular, are collated. In particular, the information page 21 has a structure similar to that of the ID card 10 described above, and when viewed in a plan view, a face image 311 and characters 313, an ID mark 314, a printing unit 300 for characters and designs, a hologram 315, and the like are displayed. It is visible. Further, although it cannot be confirmed in a plan view, the information page 21 has an IC module 200 inside, and by having an IC chip and an antenna, non-contact communication with a reader / writer is possible.

Further, an invisible ink layer 312 that may overlap at least a part of the face image 311 formed on the information page 21 is formed. A hinge portion 22 is provided at a connecting portion of the information page 21 with another page. The hinge portion 22 is made of a member that is more flexible and durable than the information page 21, and even if the information page 21 is fixed to the booklet body 20 and the page is repeatedly opened and closed, the information page 21 is damaged and the booklet is damaged. It suppresses separation from the body 20.

Although the layer structure of the information page 21 is not particularly shown, it can be similar to the structure of the ID card 10. For example, in FIG. 4, the transferred medium 1 is replaced with the base material of the information page 21, and an arbitrary printing unit 300 and a face image unit 310 composed of a face image 311 and an invisible ink layer 312 are sandwiched therein. The invisible light absorption layer 140 is laminated as described above. Further, the first transparent layer 150 is laminated on the hologram 315 so as to sandwich the hologram 315.

3. 3. Issuing system and issuing method of the first embodiment of the laminated body Next, the configuration and issuing method of the ID card issuing system according to the first embodiment of the laminated body will be described. FIG. 7 is an overall schematic view showing the ID card issuing system 50, which is the laminated body issuing system according to the first embodiment. 8 (a), 8 (b) and 8 (c) show the vicinity of the intermediate transfer sheet supply unit 52, the invisible ink layer reader 72 and the invisible light absorption layer for the ID card issuing system 50 of FIG. 7, respectively. It is a partial schematic diagram which shows the vicinity of a sheet supply part 56 and the vicinity of an invisible light absorption layer sheet supply part 57. Further, FIG. 9 is a flow chart of an ID card 10 issuance process carried out by the ID card issuance system 50.

As shown in FIG. 7, the ID card issuing system 50 supplies a transfer medium supply unit 51, an intermediate transfer sheet supply unit 52, an invisible ink layer reader 72, and an invisible light absorption layer sheet from the upstream side to the downstream side. A section 56 and a first transparent layer sheet supply section 57 are provided. The transfer medium 1 is conveyed from the upstream side to the downstream side. Further, toward the downstream side thereof, an upper conveyor 64 and a lower conveyor 62 arranged vertically, a punching unit 70, a laser light printing device 73, an ID mark reading device 74, and an ID card accumulating unit 59 are provided.

The transfer medium 1 stored in the transfer medium supply section 51 is conveyed one by one, is subjected to predetermined processing while passing through each of the above sections, and is issued as an ID card 10. After that, it is stored in the ID card collecting unit 59. Further, the ID card issuing system 50 includes a control unit 90 that is in charge of overall operation instructions and judgments. Each part and process of the ID card issuing system 50 will be described below.

(A) Transferred Medium Supply Step First, one or a plurality of transferred mediums 1 are housed in the transferred medium supply unit 51 and attached near the entrance of the ID card issuing system 50. The transfer medium supply unit 51 is a cassette that can be attached to and detached from the ID card issuing system 50, and a plurality of transfer media 1 can be stacked and held inside so that the thickness direction is up and down. One of the plurality of transfer media 1 housed in the transfer medium supply unit 51, which is arranged at the uppermost stage, is sequentially taken out by a take-out mechanism (not shown) and placed on a table-shaped transfer device 80. It is transported horizontally as it is.

(B) Intermediate transfer sheet supply step and thermal transfer step of the facial image section On the downstream side of the transfer medium supply section 51, the intermediate transfer sheet 53 can rotate to the intermediate transfer sheet supply section 52 as a roll 52a in a rolled state. Attached to. Further, the take-up roll 52b for winding the unwound intermediate transfer sheet 53 is also rotatably attached to the intermediate transfer sheet supply unit 52. As described above, the intermediate transfer sheet 53 is invisible to each of the colored ink portions 431 of the yellow ink layer (Y), magenta ink layer (M), cyan ink layer (C), and black ink layer (K) of the ink ribbon 400. By thermally transferring the invisible ink portion 432 which is the ink (X), a predetermined pattern of the face image portion 310 is repeatedly formed.

That is, in each colored ink unit 431, a portion (reverse image) corresponding to the first print layer, which is a face image 311 constituting the first identification information recognizable by visible light, is transferred to one surface of the intermediate transfer sheet 53. Has been done. Further, in the invisible ink unit 432, a portion (reverse image) corresponding to the second print layer, which is the invisible ink layer 312 constituting the second identification information recognizable by invisible light, is formed on one surface of the intermediate transfer sheet 53. It has been transcribed.

While the intermediate transfer sheet 53 is unwound from the unwinding roll 52a and wound up on the winding roll 52b side, the intermediate transfer sheet 53 is transported to a position close to the transferred medium 1 mounted on the transport device 80. At this time, the forming surface of the face image portion 310 of the intermediate transfer sheet 53 faces the transferred medium 1. Then, as shown in FIG. 8A, the hot stamp 55 provided with the heating block having a predetermined shape heats the heating block from the surface opposite to the formation surface of the face image portion 310 of the intermediate transfer sheet 53. Press. As a result, the thermal pressure of the heating block is transmitted to the transfer medium 1 in contact with the intermediate transfer sheet 53 via the intermediate transfer sheet 53, and the face image portion 310 of the intermediate transfer sheet 53, that is, the first print layer and the second print layer are transferred. It is thermally transferred onto the outermost surface of the medium 1.

The heating temperature of the hot stamp 55 when the hot stamp 55 heats and presses the intermediate transfer sheet 53 is set to 120 ° C. or higher and 200 ° C. or lower, and the pressing force of the hot stamp 55 is 0.1 kgf / cm ² or higher and 1000 kgf. It is less than / cm ² . Further, in order to satisfactorily transfer the face image portion 310 to the transfer medium 1 side, the heating temperature of the hot stamp 55 is preferably 180 ° C. or higher and 190 ° C. or lower. Further, the pressing force of the hot stamp 55 is preferably 2.2 MPa (22.43 kgf / cm ² ) or more and 3.5 MPa (35.69 kgf / cm ² ) or less for the same reason. If the heating temperature of the hot stamp 55 exceeds 190 ° C, peeling after transfer becomes difficult, and if it is less than 180 ° C, transfer defects of the image are likely to occur. Further, if the pressing force exceeds 3.5 MPa, peeling after transfer becomes difficult, and if it is less than 2.2 MPa, transfer failure of the image is likely to occur.

Further, in the step of thermally transferring the face image portion 310 of the intermediate transfer sheet 53 to the transfer medium 1 side, or immediately after the step, the face image portion 310 is close to the transfer medium 1 placed on the transfer device 80 being transferred or stopped. Although not shown, a reader / writer (reading / writing device) capable of non-contact communication with the IC chip 211 of the transfer medium 1 may be arranged at such a position. Thereby, the reader / writer can inspect whether or not the IC chip 211 of the transferred medium 1 operates normally in a state where the transferred medium 1 has passed a predetermined position within a communicable range.

From the viewpoint of preventing the thermal transfer of the face image unit 310 to the transfer medium 1 having a defect in the IC chip 211, the IC chip 211 by the reader / writer 76a is used before the thermal transfer of the face image unit 310 to the transfer medium 1 is performed. It is preferable to perform an operation test of. As a result, the face image portion 310 of the intermediate transfer sheet 53 can be thermally transferred only to the non-defective transfer medium 1, and the manufacturing yield can be improved.

(C) Invisible Ink Layer Reading Step An invisible ink layer for reading the second identification information of the invisible ink layer 312 of the face image unit 310 formed on the transfer medium 1 on the downstream side of the intermediate transfer sheet supply unit 52. A reading device 72 is provided. The invisible ink layer reading device 72 is a camera 72b that reads the intensity of visible light generated by the fluorescent color development of the invisible ink layer 312 and the illumination 72d that irradiates the face image portion 310 of the intermediate laminate 2 that is the reading object with invisible light. And.

The illumination 72d is, for example, an ultraviolet lamp such as a mercury lamp, a metal halide lamp, or an excimer lamp that can emit ultraviolet rays having a predetermined wavelength. The camera 72b may be a black-and-white or color two-dimensional CCD camera when the second identification information of the invisible ink layer 312 is a two-dimensional bar code or a two-dimensional image pattern, and the second identification of the invisible ink layer 312. If the information is a one-dimensional bar code, it may be a bar code reader.

As described above, the invisible ink layer 312 of the face image unit 310 is formed of ink that becomes visible by irradiating ultraviolet rays in a specific wavelength range, which is invisible light, to excite visible light and develop fluorescent color. .. Therefore, when the illumination 72d irradiates ultraviolet rays in a specific wavelength range, the information of the fluorescently developed invisible ink layer 312 can be easily read by the camera 72b.

That is, when the wavelength included in this specific wavelength region is set to the first wavelength, the illumination 72d irradiates the ultraviolet rays of the first wavelength toward the invisible ink layer 312 of the face image unit 310 (step S501 in FIG. 9). Next, the invisible ink layer 312 excites the invisible ink layer 312 with ultraviolet rays to develop fluorescent color, and the invisible ink layer reader 72 reads the visible light (step S502).

(D) Step of Specifying Data to be Written to the IC Chip Next, a process performed by the control unit 90 included in the ID card issuing system 50 will be described. The control unit 90 is, for example, an information processing device such as a personal computer, and includes, for example, a CPU or MPU, a memory, an input control unit, an output control unit, and the like as a hardware configuration. Here, among the memories included in the control unit 90, the rewritable non-volatile memory stores the information of the reference table as shown in FIG. 10 as an example.

The control unit 90 may be configured by a server separated from the main body of the ID card issuing system 50, and the main body of the ID card issuing system 50 and the server can communicate with each other via the Internet, a LAN cable, or the like. It may be configured in. Further, the control unit 90 may be provided with separate information processing devices for controlling the operation of the main body and for specifying the data written to the ID card 10 and for input / output.

FIG. 10 is a reference table of the face image number and the laminated body ID. This shows the correspondence between the face image number, which is a unique number for identifying the visually recognizable face image 311 in the face image unit 310, and the data written to the memory of the IC chip 211 of the ID card 10. Is. For example, the data "0013246" is written as the laminated body ID in the IC chip 211 of the ID card 10 whose face image number is "00002". The laminated body ID is a unique number for identifying the ID card 10. The information indicated by the laminated body ID is also referred to as a third identification information for convenience, in distinction from the first identification information which is the information indicated by the face image 311 and the second identification information which is the information indicated by the invisible ink layer 312.

For example, the invisible ink layer reading device 72 decodes the reading result of the two-dimensional bar code of the invisible ink layer 312 formed on the face image unit 310 of the transfer medium 1 by the control unit (step S503), and as a result, 2 It is assumed that the information indicated by the dimensional bar code is the face image number "00002". It should be noted that it may be the invisible ink layer reading device 72 itself or the control unit 90 that decodes the two-dimensional bar code of the invisible ink layer 312 and converts the data into the face image number.

At this time, the control unit 90 that has recognized the information should refer to the above-mentioned reference table stored in the memory and write the intermediate stack 2 or the ID card 10 to the memory of the IC chip 211. It is specified that the data is the third identification information of the laminated body ID "0013246" (step S504). Then, the writing instruction is given to the reader / writer 76a. This point will be described later.

(E) Step of writing to the IC chip Next, as described above, the control unit 90 specifies the laminated body ID which is the data to be written to the IC chip 211 corresponding to the two-dimensional bar code of the invisible ink layer 312. Then, the control unit 90 transfers the reader / writer 76a provided at the location where the invisible ink layer reading device 72 of the ID card issuing system 50 is provided or on the downstream side thereof to the IC chip 211 of the laminated body ID. Instruct to write. In response to this, the reader / writer 76a writes the laminated body ID, which is the third identification information, on the IC chip 211 (step S505). As a result, the laminated body ID corresponding to the information of the invisible ink layer 312 formed on the face image unit 310 can be written on the IC chip 211 of the ID card 10, and the authenticity can be easily determined by comparing both information. The card 10 can be manufactured.

(F) Invisible Light Absorbing Layer Sheet Laminating Step As shown in FIG. 8B, a roll of the invisible light absorbing layer 140 is rolled on the downstream side of the invisible ink layer reading device 72. As 56a, it is rotatably attached to the invisible light absorption layer sheet supply unit 56. On the sheet of the invisible light absorption layer 140, the hologram 315 is repeatedly thermally transferred to the surface on the side opposite to the intermediate laminate 2 side at predetermined intervals in advance. Further, two punching blades 56b and 56c for cutting the unfolded sheet of the invisible light absorbing layer 140 with a constant width along the transport direction of the transfer medium 1 can move up and down to the laser light printing layer sheet supply unit 56. Attached to.

The sheet of the invisible light absorption layer 140 unwound from the unwinding roll 56a is cut into individual sheets by the punching blades 56b and 56c, and then covered so as to cover the formation surface of the face image portion 310 of the transfer medium 1. The intermediate laminate 2 is formed by being laminated on the transfer medium 1.

(G) First Transparent Layer Sheet Laminating Process As shown in FIG. 8 (c), the sheet of the first transparent layer 150 can be rotated to the first transparent layer sheet supply unit 57 as a roll 57a in a rolled state. It is attached. Further, two punching blades 57b and 57c for cutting the drawn first transparent layer 150 sheet with a constant width along the transport direction of the transfer medium 1 can move up and down to the invisible light absorption layer sheet supply unit 57. Attached to.

The sheet of the first transparent layer 150 unwound from the unwinding roll 57a is cut into individual sheets by the punching blades 57b and 57c, and then the intermediate laminate is formed so as to cover the invisible light absorption layer 140 of the intermediate laminate 2. It is laminated on the body 2. That is, the first transparent layer 150 is laminated on the first print layer which is the face image 311 transferred to the transfer medium 1 and the second print layer which is the invisible ink layer 312 via the invisible light absorption layer 140. ..

(H) Pressing Step and Punching Step Next, as shown in FIG. 7, the first transparent layer 150 is laminated on the intermediate laminated body 2, and the hologram 315 sandwiched between the first transparent layer 150 is conveyed to the downstream side. This is further sandwiched between the upper conveyor 64 driven by the rotation of the two upper rollers 63 and the lower conveyor 62 driven by the rotation of the two lower rollers 61 provided facing each other on the lower side thereof. It is transported while being carried. Here, for example, a stainless steel plate or the like is arranged on each facing surface of the upper conveyor 64 and the lower conveyor 62. Further, a heating plate 65 is provided on the upstream side of the facing surface of the upper conveyor 64, and a cooling plate 66 is provided on the downstream side. The heating plate 65 and the cooling plate 66 are heated and cooled to predetermined temperatures, respectively, and the heat is transferred to the stainless steel plate or the like of the upper conveyor 64.

As a result, the intermediate laminated body 2 on which the first transparent layer 150 is laminated is sandwiched between the upper conveyor 64 and the lower conveyor 62 for a certain period of time while being conveyed to the downstream side, and is pressed by applying a predetermined heat pressure. .. As a result, each layer of the intermediate laminate 2 on which the first transparent layer 150 is laminated is heat-sealed to form an integrated ID card 10. Further, by being further conveyed to the downstream side, it is sandwiched between the upper conveyor 64 and the lower conveyor 62 and cooled for a certain period of time. As a result, deformation of the integrated ID card 10 due to long-term heating is suppressed.

Further, the ID card 10 that has been pressed and integrated is finished and punched by the punching blade 71 provided in the punching unit 70 in order to correctly adjust the shape of the outer edge thereof. As a result, the ID card 10 having accurate external dimensions can be obtained.

(I) Laser printing and ID mark reading process A laser light printing device 73 or an ID mark reading device 74 may be provided on the downstream side of the punching unit 70 of the ID card issuing system 50, if necessary. The laser light printing device 73 can print by irradiating the ID card 10 with laser light having a predetermined wavelength to partially blacken the invisible light absorption layer 140. Any laser can be selected, such as a carbon dioxide laser, a fiber laser, a YAG laser, and a YVO ₄ laser. As a result, the characters 313 and the ID mark 314 as shown in FIG. 1 can be easily printed.

By printing the same or corresponding information as the ID mark 314 based on the laminated body ID specified by the control unit 90, the accuracy and reliability of the authenticity determination of the ID card 10 can be improved. .. For example, the printed ID mark 314 can be recognized by an OCR reader or a camera, and the consistency between the information of the ID mark 314 of the ID card 10 and the writing information of the IC chip 211 can be inspected.

The operation of the ID card and the ID card issuing system of the first embodiment of the laminated body will be described below.

The ID card 10 has a face image unit 310 composed of a first print layer which is a face image 311 and a second print layer which is an invisible ink layer 312 on one surface of the first core layer 170 constituting the transfer medium 1. Is formed. Further, the invisible light absorption layer 140 is laminated on the first core layer 170 so as to sandwich it. Further, the first transparent layer 150 is laminated so as to face the invisible light absorption layer 140. The face image 311 constitutes the first identification information which is the unique information recognizable by visible light. Further, the invisible ink layer 312 constitutes a second identification information which is unique information recognizable by invisible light. The second identification information may be a two-dimensional bar code as an example. At this time, the invisible light absorption layer 140 absorbs at least a part of the invisible light.

The invisible light is ultraviolet light in the present embodiment, and the invisible ink layer 312 excites visible light by irradiation with the invisible light contained in a predetermined wavelength region to develop fluorescent color. As a result, the second identification information composed of the invisible ink layer 312 can be recognized by visible light. That is, in the state where the invisible light absorption layer 140 is not laminated on the ID card 10, the second identification information can be visually visually recognized by irradiating the invisible light included in a predetermined wavelength range. Alternatively, the intensity of visible light can be recognized by a camera or sensor that captures light.

On the other hand, in the final form of the ID card 10 on which the invisible light absorption layer 140 is laminated, the invisible light absorption layer 140 absorbs invisible light contained in a part of the predetermined wavelength range. Therefore, the invisible ink layer 312 does not excite the visible light and does not develop fluorescent color even if it is irradiated with the invisible light contained in this part of the wavelength range. That is, the invisible ink layer 312 cannot be recognized by visible light unless it is irradiated with invisible light having a wavelength range narrower than that in the state before the invisible light absorbing layer 140 is laminated.

In the ID card issuing system 50, as described above, the face image is formed by the invisible ink layer reading device 72 after the face image unit 310 is thermally transferred and formed on the transfer medium 1 and before the invisible light absorbing layer 140 is laminated. The face image number is read as the information of the invisible ink layer 312 of the unit 310. At this time, since the wavelength range of the invisible light irradiated to excite the visible light to the invisible ink layer 312 to develop fluorescent color is wide, the type and selection range of the illumination 72d can be expanded, and the ID card issuing system 50 can be used. Easy to build. Further, from the information read here, the laminated body ID is specified by a predetermined reference table, and this is written in the IC chip 211 of the ID card 10 as the third identification information.

As a result, the laminated body ID having a unique correspondence with the face image number, which is the information of the invisible ink layer 312 of the face image unit 310, is stored in the IC chip 211 of the ID card 10. The face image 311 and the invisible ink layer 312 of the face image unit 310 are formed on the intermediate transfer sheet 53 and thermally transferred to the transfer medium 1 at the same time. Therefore, there is no possibility that the information of the face image 311 and the invisible ink layer 312 are inconsistent with each other, and the correspondence between the first identification information of the face image 311 and the second identification information of the invisible ink layer 312 and the second identification information. The consistency of the correspondence with the third identification information, which is the stored information of the IC chip 211, is ensured. As a result, the correspondence between the first identification information, which is the face image 311 and the third identification information, which is the stored information of the IC chip 211, is guaranteed with high accuracy, which contributes to the improvement of the accuracy of the authenticity determination.

On the other hand, in the ID card 10 for which issuance has been completed, since the invisible light absorption layer 140 is laminated, the wavelength range of the invisible light irradiated to excite the visible light and develop fluorescent color in the invisible ink layer 312 can be narrowed. .. As a result, it is possible to effectively prevent the ID card 10 from being irradiated with invisible light to inadvertently visualize the second identification information of the invisible ink layer 312 or to illegally read the information.

Further, the invisible light absorbing layer 140 may be selected as one that absorbs most of the invisible light in the wavelength range in which the invisible ink layer 312 excites the visible light and develops fluorescent color by irradiating the invisible light. The term "almost no absorption" as used herein includes, for example, a light transmittance of less than 30% in the invisible light absorption layer 140. In this case, for the ID card 10 in which the invisible light absorption layer 140 is laminated and the issuance is completed, the invisible light absorption layer 140 is laminated, so that the risk of unauthorized reading of the second identification information is further reduced. can.

The above-mentioned invisible light is not limited to ultraviolet light, but may be infrared rays or the like, or other invisible light. However, when the invisible ink layer 312 excites visible light by irradiation with infrared rays contained in the predetermined wavelength range to develop fluorescent color, the invisible light absorption layer 140 is a part of the predetermined wavelength range. It is necessary to select one that absorbs infrared rays in the wavelength range. To obtain the above effects

Further, it is preferable that the invisible ink layer 312 is formed at least partially overlapping with the face image 311 in a plan view. By doing so, it is possible to suppress forgery in which the invisible ink layer 312 is left as it is and only the face image 311 is replaced with another face image. Further, as a result, the space occupied by the entire face image unit 310 can be reduced, and the degree of freedom in the face design layout of the ID card 10 can be ensured. Since the invisible ink layer 312 transmits visible light, it is unlikely that the visibility of the face image 311 will be reduced even if it is overlapped with the face image 311.

4. Another Issuing System and Issuing Method of the First Embodiment of the Laminated Body Next, another issuing system of the first embodiment of the laminated body of the present disclosure will be described. FIG. 11 is an overall schematic view showing an ID card issuing system 50a, which is a laminated body issuing system. The difference between the ID card issuing system 50a and the above-mentioned ID card issuing system 50 is that ink capable of inkjet printing between the intermediate transfer sheet supply unit 52 and the laser light printing layer sheet supply unit 56 arranged on the downstream side thereof. The head 54 is arranged. In the ID card 10a described above, the invisible ink layer 312 of the face image unit 310 is formed not by thermal transfer from the intermediate transfer sheet 53 but by application of inkjet ink from the ink head 54. Hereinafter, each part of the ID card issuing system 50a and the process will be described focusing on the differences from the above-mentioned ID card issuing system 50.

(A) ID card issuing system and ID card issuing method As shown in FIG. 11, the ID card issuing system 50a has a transfer medium supply unit 51, an ink head 54, and an invisible ink layer from the upstream side to the downstream side. A reading device 72, a reader / writer 76a, an invisible light absorbing layer sheet supply unit 56, and a first transparent layer sheet supply unit 57 are provided. Its downstream configuration is the same as the ID card issuing system 50 described above.

(B) Step of Forming Face Image and Invisible Ink Layer by Inkjet Printing An ink head 54 for injecting ink for inkjet is provided on the downstream side of the transfer medium supply unit 51. The transferred medium 1 mounted on the transport device 80 is transported to a position facing the tip nozzle of the ink head 54, and then is the first print layer which is a face image 311 by the invisible ink ejected from the ink head 54. And a second print layer, which is the invisible ink layer 312, is formed. The invisible ink layer 312 may be a two-dimensional bar code, or may be a code, character, or graphic other than the above-mentioned ID card issuing system 50. Since the configuration and process of the ID card issuing system 50a thereafter are the same as those of the ID card issuing system 50 described above, the description thereof will be omitted.

In this embodiment, since the inkjet printing method having a high degree of freedom in the printing range is used, the degree of freedom in layout between the first printing layer which is the face image 311 and the second printing layer which is the invisible ink layer 312 in the card 10a is further increased. It can be expanded further. Further, as described above, even when the face image 311 is formed on the transfer medium 1 by thermal transfer of the intermediate transfer sheet and the invisible ink layer 312 is formed by inkjet printing, the first printing layer and the second printing are performed. It also has the effect of increasing the degree of freedom in layout with layers.

5. Issuance system and issuance method of the second embodiment of a laminated body Next, the issuance system and issuance method of the information page which concerns on the 2nd Embodiment of this disclosure, or the booklet containing this, will be described.

The production and issuance of the information page according to the second embodiment is substantially the same as the above-mentioned ID card issuing system 50 and its issuing method in which the transferred medium 1 is replaced with the base material of the information page 21. Can be done at. After that, the issued information page 21 may be collated with other pages or the like to form a booklet 20.

Alternatively, the information page 21 is first manufactured in the form of a booklet 20, and then the information page 21 is fixed in an open state, whereas the above-mentioned ID card issuing system 50 and issuing method are used. The information page 21 can also be issued by the same system and method. The information page 21 and the booklet 20 issued in this way naturally have the same effects as the ID cards 10 and 10a described above.

6. Laminated body inspection system and inspection method Next, the ID card inspection system according to the laminated body of the present disclosure will be described. FIG. 12 is a schematic view showing an ID card inspection system 50b, which is a laminated body inspection system. Further, FIG. 13 is a flow chart of the authenticity determination process of the ID card 10 or 10a carried out by the ID card inspection system 50b.

(A) ID card inspection system and ID card authenticity determination method As shown in FIG. 12, the ID card inspection system 50b has an ID card supply unit 51a, a reader / writer 76c, and an invisible ink layer from the upstream side to the downstream side. A reading device 72a and an ID card accumulating unit 59a are provided. The ID card 10 or 10a mounted on the transport device 80a is transported from the upstream side to the downstream side. The description will be given by taking the ID card 10 as an example, but the same applies to 10a. The ID card inspection system 50b includes a control unit 90a that is in charge of overall operation instructions and judgments. Hereinafter, each part and the process of the ID card inspection system 50b will be described.

(I) ID card supply process First, one or a plurality of ID cards 10 are stored in the ID card supply unit 51a and attached near the entrance of the ID card inspection system 50b. The ID card supply unit 51a is a cassette that can be attached to and detached from the ID card inspection system 50b, and a plurality of ID cards 10 can be stacked and held inside so that the thickness direction is the vertical direction. However, the ID card supply unit 51a may be provided with only an insertion port, and may have a structure in which the manually inserted ID card 10 is drawn into the inside by a transport roller or the like.

One of the plurality of ID cards 10 stored in the ID card supply unit 51a, which is arranged at the uppermost stage, is sequentially taken out by a take-out mechanism (not shown), placed on a table-shaped transfer device 80a, and horizontally as it is. Transported in the direction. However, as described above, the ID cards 10 may be manually inserted one by one from the insertion slot of the ID card supply unit 51a and transported while being sandwiched between the upper and lower rollers.

(Ii) Step of reading stored data of IC chip Next, the ID card 10 is conveyed to a position close to the reader / writer 76c. The reader / writer 76c reads out a predetermined laminated body ID stored in the IC chip 211 by non-contact communication with the ID card 10 (step S511). As described above, the laminated body ID is the unique information for specifying the ID card 10, and is the third identification information. The read information is transmitted to the control unit 90a for comparison and determination described later.

(Iii) Invisible Ink Layer Reading Step Next, the ID card 10 is conveyed to the downstream side thereof, and together with the camera 72c of the invisible ink layer reading device 72a for reading the second identification information of the invisible ink layer 312 of the face image unit 310. Move to the opposite position. The invisible ink layer reading device 72a has the same structure as the invisible ink layer reading device 72 of the ID card issuing system 50. That is, it includes an illumination 72e that irradiates the face image unit 310 of the ID card 10 that is the object to be read with invisible light, and a camera 72c that reads the intensity of visible light generated by the fluorescent color development of the invisible ink layer 312. However, the illumination 72e irradiates invisible light in a wavelength range narrower than the possible wavelength range of the invisible light emitted from the illumination 72d of the invisible ink layer reader 72 of the ID card issuing system 50.

The illumination 72d irradiates the invisible ink layer 312 of the face image unit 310 with ultraviolet rays of the first wavelength included in the specific wavelength range. On the other hand, from the illumination 72e, it is necessary to irradiate the invisible ink layer 312 of the face image unit 310 with ultraviolet rays having a second wavelength included in a wavelength region narrower than the specific wavelength region. The ultraviolet rays of the second wavelength mean that the invisible ink layer 312 excites visible light to develop fluorescent color, and the invisible light absorption layer 150 hardly absorbs the ultraviolet rays in the wavelength range. do. As mentioned above, the degree of absorption is almost nonexistent.

As described above, the illumination 72e of the invisible ink layer reader 72a irradiates the invisible ink layer 312 of the face image unit 310 of the ID card 10 with ultraviolet rays having a second wavelength (step S512). Then, the intensity of the visible light that is excited and fluorescently colored by the invisible ink layer 312 is read by the camera 72c (step S513). Based on this reading information, the invisible ink layer reading device 72a or the control unit 90a decodes the second identification information configured by the invisible ink layer 312 (step S514). Further, the control unit 90a identifies the stack ID corresponding to the second identification information based on the same reference table as the control unit 90 of the ID card issuing system 50 stored in its own memory or the like (step S515).

The control unit 90a is specified from the value of the laminate ID, which is the third identification information stored in the IC chip 211, and the second identification information configured by the invisible ink layer 312, based on the correspondence of the reference table. (Step S516). As a result, if they match or correspond correctly, the success process is performed assuming that the authenticity determination is successful (step S517).

The success process is not particularly limited, and examples thereof include permission for various electronic procedures after that, permission for passing through the gate, permission for continuing another authentication process after that, or simplification thereof. On the other hand, if they do not match or do not correspond correctly, the failure process is performed assuming that the authenticity determination has failed (step S518). The failure processing is also not particularly limited, and examples thereof include suspension of various electronic procedures after that, prohibition of passing through the gate, and continuation or strengthening of another authentication processing thereafter.

In addition, in the invisible ink layer reader 72a, in addition to the illumination 72e, an illumination 72f capable of irradiating invisible light having a third wavelength, which is a wavelength range different from the second wavelength, may be further provided. The third wavelength is included in the wavelength range that the first wavelength can take, but is included in the wavelength range that is not included in the wavelength range that the second wavelength can take. That is, in the state before the invisible light absorption layer 140 is laminated, the invisible ink layer 312 is excited by irradiation with invisible light of either the second wavelength or the third wavelength, and fluorescent color is developed.

However, with respect to the ID card 10 after the invisible light absorption layer 140 is laminated, the invisible ink layer 312 can be fluorescently colored by irradiation with invisible light of the second wavelength, but the invisible light of the third wavelength is emitted. Fluorescent color cannot be developed at the time of irradiation. Therefore, it is possible to inspect the ID card 10 whether or not the second identification information of the invisible ink layer 312 can be read by the camera 72c while switching the illuminations 72e and 72f to each other.

Here, for example, if it can be read when the illumination 72e is irradiated and cannot be read when the illumination 72f is irradiated, it can be determined that the ID card 10 is not forged with the correct material composition. On the other hand, if it is readable or unreadable at the time of irradiation of the illuminations 72e and 72f, at least one of the materials of the invisible ink layer 312 or the invisible light absorption layer 140 is different from the normal one. , It can be judged that it may be forged. This makes it possible to determine the authenticity of the ID card 10 with higher reliability.

(B) Operation of the ID card inspection system The ID card inspection system 50b compares the second identification information formed by the invisible ink layer 312 formed on the face image portion 310 of the ID cards 10 and 10a of the first embodiment. It can be read by irradiating it with ultraviolet rays of the second wavelength, which is a narrow wavelength range. Further, the third identification information stored in the IC chip 211 can be read by non-contact communication. Further, the ID card inspection system 50b includes a reference table for defining a correspondence relationship between the second identification information and the third identification information, for example, a third identification corresponding to a face image number which is a specific example of the second identification information. It is possible to specify the laminated body ID which is a specific example of the information.

As a result, the ID card inspection system 50b stores information specified based on the reference table from the second identification information acquired by reading the invisible ink layer 312, for example, the first laminated body ID and the IC chip 211. When the ID card 10 matches or correctly corresponds to the second laminated body ID which is the third identification information, it can be determined that the ID card 10 is a regular laminated body. In other cases, it can be determined that the ID card 10 is not a regular laminated body.

Therefore, the ID card inspection system 50b according to the present embodiment is compared with a method of directly comparing and collating the first identification information, which can be a large capacity if converted into data, such as the face image 311, with the third identification information of the IC chip 211. According to the above, the ID card 10 can be inspected easily in a short time. Further, since the second identification information associated with the first identification information cannot be visually recognized by irradiation with visible light, the design of the ID card 10 is not restricted, the design can be improved, and the degree of freedom in layout can be expanded.

An image was formed by a commercially available video printer using a thermal transfer sheet in which yellow, magenta, and cyan dye layers were sequentially provided on the receiving layer of the intermediate transfer sheet. After that, the image-formed receiving layer surface and the transferred medium shown below are combined, and the transfer portion composed of the release layer, the protective layer and the receiving layer is transferred to the transferred medium by a heat roll method. The face image portion of Example 1 was prepared. Of these, the invisible ink layer was assumed to form a two-dimensional bar code. The transfer medium is a card-shaped member in which the first core layer is polycarbonate and is formed to be slightly larger than the card size having an overall thickness of 0.8 mm.

Next, the following invisible light absorption layer was directly laminated on the transfer medium on which the face image portion was formed, without passing through the laser beam printing layer, by applying heat pressure.

<Resin particles>
63 g of methyl methacrylate (MMA) as a monofunctional (meth) acrylic monomer (70% by weight based on 100% by weight of the monomer mixture) and ethylene glycol dimethacrylate as a polyfunctional vinyl monomer (70% by weight). EGDMA) 27 g (43 parts by weight with respect to 100 parts by weight of a monofunctional (meth) acrylic monomer; 30% by weight with respect to 100% by weight of the monomer mixture) and 2,2'as a polymerization initiator. -Azobis (2,4-dimethylvaleronitrile) 0.2 g was added and mixed to prepare a monomeric composition.

In a separable flask having an internal volume of 500 ml, 270 g of water as an aqueous medium, 8.7 g of tricalcium phosphate as a suspension stabilizer, and 0.08 g of sodium dodecylsulfonate as a surfactant were placed. The monomer composition was added to the contents of this separable flask. The contents of the separable flask were stirred at high speed with a high speed stirrer to form fine droplets of the monomer composition. Polymerization was carried out by heating the contents of the separable flask at 50 ° C. for 5 hours while stirring. Hydrochloric acid was added to the obtained resin particles to decompose the suspension stabilizer, and then the resin particles were washed with water. After washing, the solid was separated by centrifugal dehydration. The obtained solid was vacuum dried at 60 ° C. for 10 hours to obtain resin particles having a volume average particle diameter of 8 μm and a coefficient of variation (CV value) of 35%.

Dipentaerythritol hexaacrylate, which is an ultraviolet curable resin binder (photopolymerizable polyfunctional monomer), a photopolymerization initiator, the above-mentioned resin particles, and methyl ethyl ketone as a diluent are sufficiently mixed in the following formulation. A coating composition was prepared.

This coating composition was applied onto a PET film having a thickness of 188 μm using a No. 6 (# 6) bar coater to form a layer of the coating composition. The layer of the coating composition is heated at 60 ° C. for 1 minute to dry, and then dried by irradiating the dried layer of the coating composition with ultraviolet light having an irradiation amount of 500 mJ / cm ² with a high-pressure mercury lamp under a nitrogen purge. The layer of the coating composition was cured to obtain a film of an invisible light absorbing layer having surface irregularities.

The film of the invisible light absorption layer was laminated on the transfer medium on which the above-mentioned facial image portion was produced, and the two were integrated by applying heat pressure, and the finish was removed to complete the ID card.

(Ii) Example 2
Except for the fact that the fluorescent dye 1 was reduced from 1.0 part to 0.7 part and 0.3 part of the fluorescent dye 2 (Sr3 (PO2) 3Cl: Eu-based fluorescent pigment) was added in the ink coating liquid for the adhesive layer. In the same manner as in Example 1, a facial image portion was prepared on the transfer medium. Further, the lamination of the invisible light absorption layer on the transfer medium was the same as in Example 1.

(B) Results of UV Irradiation and Reading Test on Samples As UV lamps for UV irradiation, an ultraviolet lamp 1 having a peak near a wavelength of 254 nm and an ultraviolet lamp 1 having a peak near a wavelength of 365 nm were used. It was confirmed whether or not the invisible ink layer forming portion of the ID card could be read by a commercially available visible light compatible two-dimensional bar code reader when irradiated with these ultraviolet lamps. The sample of Example 1 has a fluorescent dye 1 (Y203: Eu-based fluorescent pigment) that excites the invisible ink layer only with ultraviolet rays of 254 nm to fluorescently develop red visible light. In addition, the sample of Example 2 is a fluorescent dye 2 (Sr3 (PO2) 3Cl: Eu system) that excites both 254 nm and 365 nm ultraviolet rays in addition to the fluorescent dye 1 and fluorescently develops blue-purple visible light. It also has a fluorescent pigment).

Further, the invisible light absorption layer of the samples of Examples 1 and 2 absorbs electromagnetic waves having a wavelength shorter than this with a wavelength of about 300 nm as a boundary so that the transmittance is less than 10%, and electromagnetic waves having a wavelength higher than this. Has a property of transmitting so that the transmittance is 80% or more. From this, it was confirmed that when the sample of Example 1 was irradiated with the ultraviolet lamp 1, the two-dimensional bar code of the invisible ink layer was fluorescently developed in red and could be visually recognized, and the reading by the two-dimensional bar code reader could be performed normally. bottom. At this time, it is presumed that only the fluorescent dye 1 is fluorescently colored. Further, it was confirmed that when the sample of Example 1 was irradiated with the ultraviolet lamp 2, the two-dimensional bar code of the invisible ink layer could not be visually recognized and could not be read by the two-dimensional bar code reader. In this case, it is presumed that neither the fluorescent dye 1 nor the fluorescent dye 2 developed fluorescent color.

On the other hand, when the sample of Example 2 was irradiated with the ultraviolet lamp 1, it was confirmed that the two-dimensional bar code of the invisible ink layer was fluorescently developed in reddish purple and could be visually recognized, and that the two-dimensional bar code reader could normally read the sample. bottom. In this case, it is presumed that both the fluorescent dye 1 and the fluorescent dye 2 fluorescently develop red and bluish purple, respectively, and both of them appear to be mixed. Further, it was confirmed that when the sample of Example 2 was irradiated with the ultraviolet lamp 2, the two-dimensional bar code of the invisible ink layer was fluorescently developed in bluish purple and could be visually recognized, and the reading by the two-dimensional bar code reader could be performed normally. bottom. In this case, it is presumed that only the fluorescent dye 2 develops a fluorescent color.

From these results, for example, if an ID card as in Example 1 is adopted in an ID card issuing system, the second identification information can be obtained by irradiating a wide range of ultraviolet rays of 254 nm and 365 nm at the stage before laminating the invisible light absorbing layer. It can be read. However, after issuing the ID card after laminating the invisible light absorption layer, the second identification information can be read only by irradiation with ultraviolet rays in a narrow range of, for example, only 254 nm, ensuring the ease of issuing work and ensuring the ease of issuing the ID card product. It is possible to ensure security at the same time.

Further, when an ID card as in the second embodiment is adopted in the ID card issuing system, the second identification information is obtained by irradiating a wide range of ultraviolet rays of 254 nm and 365 nm both before and after laminating the invisible light absorbing layer. Can be read. However, after issuing the ID card after laminating the invisible light absorption layer, the range of visible light that develops fluorescent color becomes narrower, and the visibility and readability deteriorate by that amount, and the security of the ID card product is improved from this point. Can be maintained.
